IMPROVEMENT IN REClPROCATlNG-CHURN ATTACHMENTS.

Specification forming part of Letters Patent No.

205,687, dated July 2, 1878; application filed May 7, 1678.

To all whom it may concern:

Be it known that I, STEPHEN D. SAXBY, of Trenton, in the county ofGrundy and State of Missouri, have invented a certain new and usefulAttachment to Reciprocating Ghurns; and I do hereby declare that thefollowing is a clear and exact description of my invention, which willenable others skilled in the art to which it pertains to make and usethe same, reference being had to the accompanying drawing, which forms apart of this speci fication, and in which- Figure l is a perspectiverear view. Fig. 2 is a front view, and Fig. 3 is a perspective view ofthe case which covers my attachment detached from the churn.

Similar letters of reference indicate corresponding parts in all thefigures.

This invention relates to devices for operating reciprocating churns;and it consists in the construction and combination of parts of aremovable and adjustable attachment which may be secured upon anyreciprocating churn, and is connected with the dasherstafi for thepurpose of imparting to this a regular, quick, and even up-and-down orreciprocating mo tion, substantially as hereinafter more fullydescribed.

In the drawing, A is the churn, and a the dasher-statf. which projectsup through a central perforation in the cover I), as usual. To one sideof the churn A is secured a semicircular table or bracket, B, held inplace by screws 0.

Upon the bracket B is secured adjustably a plate, 0, having a slot, d,through which passes a set-screw, e. by means of which plate 0, whichsupports the operating mechanism, may be adjusted upon bracket B, so asto be brought nearer to or farther from the axis of the churn, accordingto the size, diameter, and capacity of this.

Made preferably in one piece with the bent part of plate 0, at rightangles to bracket B, is a standard G, to one side of which is bolted,screwed, or riveted a frame consisting of the pieces D E.

F is a gear-wheel, the shaft of which is journaled in hearings in theframe-pieces O D, and which meshes with a pinion, G, keyed upon theshaft y of the fly-wheel H, which is hung between the standards orframe-pieces D E, and has a pin, h, inserted into and pro-. jecting fromits front face.

Pin h is inserted into and engages with a casting, I, consisting of twoparallel arms, t i, united bya vertical cross-piece, k, which has avertical rib or flange projecting into a slot, l, in the frame-pieceE,this slot serving as a vertical guide for the cam-piece I, to the clampm m of which the dasher-staif is secured. This clamp consists of astationary leaf, m, and a hinged leaf, m, which may be clamped togetherby a thumb-screw, n,-so as to securely hold the dasher-staff a in anygiven position. By loosening screw it the staff may be adjusted in theclamp as circumstances may direct.

The gear-wheel F is operated by a crank, o, and handle 19.

To keep the entire operating mechanism free from dirt or dust, a cover(represented in Fig. 3) 's inserted upon the attachment, which is soconstructed as to fit closely all parts there of, and provided with aslot, 1', in its front side, through which clamp m m projects andreciprocates vertically.

This attachment is simple, strong, and dnra ble in its construction, andby it the operation of churning is greatly facilitated. By the aid of afew wood-screws it may be secured upon any ordinary reciprocating churn,and may be adjusted so as to fit any length of dasherstatf or size andcapacity of churn. It is compact, taking up but little room and byproviding the fly-wlreel H with a series of holes at different distancesfrom its center the? pin h may be so adjusted in said holes (these beingprovided with a female and the pin with a male screw thread) that thestroke of the dasher-staff may be easily regulated.

Having thus described my invention, I claim and desire to secure byLetters Patent of the United States- In a reciprocating churn, thecombination, with the frame 0 D E, having the longitudinal or verticalslot 1 and the casting I i i, arranged crosswise to the slot 1, andprovided wit-h a ribbed connecting-piece, la, fitting into the saidslot, of the fiy-wheel H, having the cam stud or projection h, pinions FG, and dasher-staff a, connected to the upright E of the above-mentionedframe, substantially as shown and described, for the purpose specified.

STEPHEN D. SAXBY.
